Rhode Island Department of Education Lesson Plan Lesson Title: Molecular Geometry 2 State Standards:(GLEs/GSEs) GSE - PS1 (9-11) - 4 National Standards: Context of Lesson: This class is the second day on molecular geometry. In the last class the students worked on an inquiry task on molecular geometry. In this class I will be using the worksheets that the students filled out to go over the actual terms for molecular geometry and to clear up any misconceptions about the molecular geometry of compounds. Opportunities to Learn: Depth of Knowledge: Prerequisite Knowledge: Plans for Differentiating Instruction: Accommodations and modifications: Environmental factors: Materials:
Objectives:
The students will determine the molecular geometry of compounds.
The students will explain why compounds are shaped the way they are using VESPR theory.
Instruction: Opening:
Review what the students did in the last class.
The inquiry task.
What did the students learn?
What was confusing?
In todays class we will take a closer look at molecular geometry.
Yesterday’s activity got you thinking about molecular geometry and now we will take what you learned and connect it to some new terms and information.
Engagement:
Draw several different molecules on the board.
Carbon Dioxide CO2, Water H2O, Ammonia NH3, Methane CH4
Review: What types of bonds are in each of these?
Take out a ball and stick model of each of these molecules.
How are they shaped?
Give the real terms.
Linear.
Bent.
Pyramidal.
Tetrahedral.
Why are they shaped this way?
Types of bonds.
Lone pairs of electrons.
VESPR theory.
The repulsion between electron pairs causes molecular shapes to adjust so that the valence-electron pairs stay as far apart as possible.
Give the students worksheets with more examples.
Work in groups but must be completed for homework.
Walk around to the groups and help out.
Closure:
I noticed that many of the students were having trouble with...
Go over that aspect with the class briefly.
Remind the students that the worksheet has to be completed at home.
Assessment: The students will be assessed through a worksheet on molecular orbitals that will be started in class and finished for homework. Reflections: (only done after lesson is enacted) Student Work Sample 1 – Approaching Proficiency: Student Work Sample 2 – Proficient: Student Work Sample 3 – Exceeds Proficiency:
